While following this discussion, I have also looked long and hard at our AIX 5.1 (H50 with 3GB memory and 2GB page space) running TSM 4.1.2.9. I am submitting vmtune and vmstat information. Any comme

John, Based on my experience, you're doing fine. * Your system is doing zero paging to/from disk (pi and po are both zero consistently); * Your scan/free ratio (sr/fr) is about 2, which is OK. Rule o
IMHO, your box looks overloaded: 1. you always have 20+ runnable processes 2. user + system exceeds 95% most of the time 3. you are always searching and freeing memory 4. with F - f / R, you only hav

I am trying to figure out what these are. The defaults are not good on a large server. The suggestion is figure out how much memory does dsmserv need and then work from there. So lets take the exampl

Actually, the dsmserv task is 400MB including the 256MB pool according to topas. If I add up all of the processes on the system I about 512MB. This means my maxperm should be at least down to 75 (per

Mark, I am sure your recommendations will bring rain. But, it is the most definitive response to this question yet. This thread is going to be a gold mine when done. I bet there are hundreds of TSM s
Paul, When tuning "maxperm", one important thing should be noted: "maxperm" is not the limit on cached file pages! Under heavy JFS file I/O, the file cache can grow up to "maxperm" by paging out proc
